Comparison of CO2 Emissions from Aircraft, Trucks, and Ocean Vessels (Unit: grams/ton-km)

Compared to other modes of transport, ocean shipping can transport larger volumes of cargo at once and is a generally environment-friendly mode, with lower emissions per unit load of CO2 and other air pollutants.

However, with growth of the world economy spurred by the development of emerging markets, overall world ocean cargo traffic continues to increase. Seaborne trade has exceeded 10 billion tons, and we anticipate further increases in the future. As seaborne trade increases, CO2 emissions will rise in step with growing energy consumption. This can exacerbate pressing environmental issues. CO2 emissions from merchant vessels account for about 2% of global emissions, and the shipping industry must do more to protect the environment. MOL strives to control emissions of pollutants through initiatives such as the adoption of advanced technologies and slow steaming. In FY2016, we reduced CO2 emissions per tonmile by 6.5% in comparison with the previous year. We will proactively promote the adoption of technologies to reduce our environmental impact through the "ISHIN NEXT - MOL SMART SHIP PROJECT -" launched last year. We are also committed to entering environmental business areas such as renewable energy and develop them as a core business in the future.
